A demented retelling of the biblical tale of Abraham and Isaac? Something taboo from a Lovecraftian mind? Or the horrific anti-Father's Day tale from an angry single mother? No on all counts, but something more horrific. 2015's "Heir," from Fatal Pictures is an uncomfortable short horror film (14 minutes) that is making the rounds at festivals and accumulating award nominations. With terrific acting and brilliant direction by Richard Powell, this frightening tale hooks us within seconds and then stays with us.
